Customers are generally requiring a variety of products, earlier due date, and lower price. A manufacturing process needs the efficient scheduling to meet those customer's requirements. This study proposes the novel algorithm named MJA(Minimum Job completion time and AGV time) that increases the performance of machines and AGV(Automated Guided Vehicles) in many kinds of job types. MJA optimizes the bottleneck of machines and efficiency of AGV with considering two types of dispatching at the same time. Suggested algorithm was compared with existing heuristic methods by several simulations, it performed better for reducing the time of tardiness.

A group scheduling problem, which is production scheduling problem associated with the concept of group technology, is studied under due date constraints in multi-stage manufacturing systems. The purpose of this paper is to develop and evaluate a practical heuristic procedure for determining group sequence and job sequence within each group to minimize total tardiness in multi-stage manufacturing systems. A heuristic algorithm has been developed by introducing the concept of relative measures of job tardiness and group tardiness for job sequencing and group sequencing, respectively. A numerical example is shown to illustrate the proposed procedure. The heuristic algoirthm is tested by comparisons with problems with known optimal solutions and also with random group schedules for a set of large-size problems. Results indicate that the proposed heuristic algorithm provides good solutions with small computational requirements, and thus is viable for large size problems in practice.

ICAO(International Civil Aviation Organization) established ICAO LPRs(Language Proficiency Requirements) which is an international standard of English for aviation to promote the aviation safety. The Republic of Korea government amended the aviation law on the 8th of November, 2005 and made EPTA(English Proficiency Test for Aviation) as a follow up action. Purpose of this research is analysing the problem of EPTA and improving it. This investigation takes a look at the current ICAO LPRs and compares the difference between EPTA and other global English proficiency requirements for aviation. The result indicated that there is a discordance between the standards of ICAO and EPTA. Also, the global English proficiency reqirements for aviation and EPTA had differences which required improvements. The study suggests to replace more job relevant questions in the EPTA and reform the level system of EPTA.

간호간병통합서비스병동과 일반병동 간호사의 직무스트레스와 직무만족을 확인하여 효과적인 간호인력 관리를 위한 자료를 제공하고자 실시되었다. 300병상 미만의 4개 병원에서 간호간병통합서비스병동 간호사 62명과 일반병동 간호사 62명의 설문지를 수집하여 분석하였다. 간호간병통합서비스병동 간호사는 일반병동 간호사보다 직무만족이 높았고, 특히 보수, 전문성, 행정요구, 자율성, 업무요구, 상호작용 영역에서 높았다. 일반병동 간호사는 간호간병통합서비스병동 간호사보다 직무스트레스 중 간호업무, 의사와 갈등, 환자와 보호자 영역에서 높았고, 간호사 대우 영역에서 낮았다. 직무만족과 직무스트레스의 관계는 일반병동 간호사에서만 유의한 역상관관계로 직무스트레스가 낮을수록 직무 만족은 높았다. 따라서 간호사들의 직무스트레스를 낮추고 직무만족 향상을 위해 명확한 업무규정에 의한 업무수행, 과도한 업무부담의 감소, 적절한 보상, 상위 교육 지원이 필요하다.

도서관 환경이 변화하면서 목록 업무가 달라지고 이에 따라 목록사서의 역할 및 자격 요건도 확대되고 있다. 본 연구에서는 달라지고 있는 목록사서의 역할과 자격 요건을 문헌 연구와 미국 대학도서관 목록사서직의 광고 내용 분석을 통해 살펴보았다. 목록사서에게 필요한 직무능력은 전통적인 분류 및 목록도구에 관한 지식에 컴퓨터와 네트워크 활용 기술이 더해지면서 감독기술, 관리능력, 커뮤니케이션 기법, 연구 및 학술활동의 노력, 새로운 환경으로의 적응력, 문제해결능력, 융통성등을 요구하는 것으로 나타났다. 도서관에서 원하는 유능한 목록사서을 양성해내기 위한 목록교육을 재고해야만 할 시점이다.

The study measured a subway construction worker's Macpa stress by Heart Rate Variability measuring instrument and conducted a survey of Korean job stress from subway construction workers. Also, the study analyzed the relationship between Macpa stress index and Korean job stress result and suggested managing stress method for each item. According to National Statistical Office data, the first line subway in Seoul was started to open in 1974. The extended total length is 996 kilometers until 2019. Many aged workers are currently working at subway construction sites due to the avoidance of young workers since the past until now. It means that the elderly has a substantial portion among subway construction workers. The productivity has been adversely affected by health problems due to the aging of workers, job stress due to heavy work, and personal health problems. So, the regulation and policies on job stress health management are being strengthened. The data were measured Macpa stress by machine measuring heart rate variability and conducted Korean job stress survey(shortened) from Sa-sang to Ha-dan line Busan subway construction workers for analyzing the relationship. Independent variable were age, job duration, job position, employment type, working type in this study. Macpa's dependent variable was stress index and Korean job stress survey(shortened)'s dependent variables were job requirements, job autonomy, relationship conflict, job instability, organizational structure, inappropriate compensation, working place culture, and total score. SPSS 12.0 K Statistics Program was used for statistical analysis. Kruskal-wallis test, a nonparametric statistical analysis, was used because the data are difficult to be assumed as normal distribution. As a result, the paper indicated the significant correlation between Macpa stress index and Korean job stress(short version). The elderly workers presented higher Macpa index and higher job stress due to aging and heavy-duty work. The majority workers were daily workers who had unstable working condition and uncertainty about the future. The study suggested a manual that could reduce job stress for subway construction workers and future study deriving management tool through analyzing job stress factor is necessary.

이번 연구는 직무착근도의 척도를 국내 실정에 적절하게 적용할 수 있도록 수정 보완하여, 치과위생사의 직무착근도를 평가할 수 있는 도구를 개발하고 타당도와 신뢰도를 평가하고자 시행하였다. 직무착근도 원 도구 25문항을 번역한 후 내용분석 및 내용 타당도 검증을 통하여 8문항을 삭제하고 5문항을 수정하여 총 17문항을 분석하였다. 연구 결과 탐색적 요인분석에 의해 요인 적재량이 0.4 이하인 4개의 문항은 삭제되었으며, 도구의 적합성, 연계, 희생 요인들로부터 추출된 문항들이 새롭게 혼합되어 구성되었다. 치과위생사를 위한 직무착근도의 하위요인으로는 '조직 적합성', '직무 연계성', '직원 관계성'으로 구분되었다. 또한 확인적 요인분석을 통한 모형의 적합도는 대체로 기준을 충족하였다(${\chi}^2=257.394$ [df=62, p<0.001], RMR=0.059, RMSEA=0.107, CFI=0.887, GFI=0.870, AGFI=0.810, NFI=0.857, IFI=0.888, TLI=0.858). 내적일관성을 검증한 결과 Cronbach's ${\alpha}$는 착근도의 하위요인인 조직 적합성 0.866, 직무 연계성 0.916, 직원 관계성 0.669로 나타나 신뢰할 만한 수준의 측정도구임을 나타냈다. 이상의 결과에 따라 치과위생사의 직무착근도 측정도구의 타당도와 신뢰도는 적합하다고 검증되었다. 향후 우리나라 치과 내 조직원들의 이직 및 장기근속에 대한 연구에 활용되어 의료기관의 병원 경영 및 직원 관리에 보탬이 될 것으로 생각된다.

Objectives: This paper aims to investigate the influence on stress hormones of job stress resulting from firefighting duties, as well as the degree of such influence. Methods: KOSS-26 and stress hormones such as norepinephrine (NE), epinephrine (EPI), adrenocorticotrophic hormone (ACTH), and cortisol were analyzed for 191 male firefighters from the western area of Incheon, the Incheon Industrial Complex, and Bucheon, Korea. Job stress and stress hormones were compared between a office working group and field-working group. Results: There was no significant difference in EPI and ACTH between the two groups. Change of stress hormones prior to engaging in typical duties, following typical duties, and immediately after field activities was examined. All the EPI, ACTH, and cortisol showed statistically significant changes with time, but not NE in the blood. In the field-working group, the cortisol levels in the blood of the firefighting and rescue groups showed notable differences depending on the time at which the measurements were taken. Conclusion: The differences in stress hormone levels depending on the type of duties of the firefighters were identified. Thus, interventions proper to job requirements is required in order to ease stress.
